Congrats to the particledb team for getting this far and thanks to @aphyr for the analysis.
It takes gumption to build a new storage engine. I remember when etcd[0] first made it's way into @aphyr's cross-hairs. We took all of the input very seriously because we knew that a data store which is untrustworthy is useless.
Resolving these issues likely won't be easy, but if you can get to the point where you walk away from Jepsen unscathed the trust in your software will be greatly amplified.

Finding issues is normal. But the bold claims they had on their website is what makes this a bust.
Right, when Rachael Gunn (Raygun) embarrassed Australia and the whole of breakdancing on the olympic stage, the nice thing to say would have been "congrats on getting this far, fixing the issues won't be easy, etc..." but what really should be said something like "I'm not sure how it got to this point, but everything about this is wrong, and you should probably focus on something else".
Reads like investor cope. And the OG etcd was a disaster that needed better engineers to completely rewrite. The surviving project is an entirely different lineage.
